DC20 - CUSTOM SERIES1/4” Air operated diaphragm pump.
PROVEN SUPERIOR PERFORMANCE I SIMPLE I RELIABLE I DURABLE I COMPACT I SMOOTH RUNNING I COST EFFICIENT
CUSTOM SERIES SETS NEW STANDARDS IN DIRECTFLO® TECHNOLOGY
• Low start up pressure.• Low air consumption.• Shorter strokes.• Performs well at lower pressures.
• Improved resistance to abrasion.• Minimum pulsation and vibration.• Reduced noise.
Exclusive Directflo® pump technology.
THE NEW CUSTOM SERIES MAKE THE DIFFERENCE THROUGH:LOW START UP PRESSURE. Adjustable flow rate when regulating the air pressure.
COMPACT DESIGN. Ideal for OEM installation applications.
INCREASED RELIABILITY. No stall, non icing, start up reliability and longer duration. A must in industrial processes.
EFFICIENCY. Low air consumption.
MAXIMUM VERSATILITY. Orientable air valve and inlet-outlet ports offer multiplemounting options.
EASY SERVICING. Exclusive Directflo® central flow design allows servicingdiaphragms and air motor without dismounting it from the fluid line.
